With the development of the modern building materials market and our use of various paving materials in the industry, paving tiles, as a type of clay brick, are the product of continuous optimization of products and continuous upgrading of traditional skills. The following describes the preventive measures against alkali in paving slabs:
1. When paving paving slabs, the dovetail trough should be filled with cement to prevent the accumulation of water in the unfilled places and causing anti-alkali;
2. Don't construct in rainy weather, pay attention to the paving slabs after construction, and spray water;
3. If the paving slabs show pan-alkaline alkali, it should be cleaned with oxalic acid and hydrochloric acid in a ratio of 3: 1, with a total concentration of 1%. It is better to use special anti-pan-alkali cement.
The paving bricks we usually use are generally made of high-quality clay and even purple sand terracotta fired at high temperature. The natural clay is used as the main component and quartz, feldspar and other aggregates are used. When we are paving, we must also take good construction measures.
